Yes you're right about drm ! As you may have suspected I'm totally against drm and closed systems because I see them as a serious limitation of freedom.
I want a device that allows to read a large variety of content from a large variety of sources.
About windows mobile os , well I work on a windows 2000 equipped pc, I'm writing on a windows xp system , my girlfriend uses a notebook and a smartphone both with that omnipresent branded os, so if I can use an electronic gadget windows free I feel a little better.
Linux os seems to be much more flexible and less closed than windows,just my opinion(I used to work on a linux system before management opted for windows). Bye
